Anti-overbilling

Overbilling can occur when a subscriber returns their IP address to the IP pool. Before the billing server closes it, the subscriber's session is still open and vulnerable. If an attacker takes control of the subscriber's IP address, the attacker can send or receive data and the subscriber will be billed for the traffic.

Overbilling can also occur when an available IP address is reassigned to a new mobile station (MS). Subsequent traffic by the previous MS may be forwarded to the new MS. The new MS would then be billed for traffic it did not initiate.
